Process for the manufacture of a dry mixture for insulating stucco or plaster

Abstract

A process for the manufacture of a thermally insulating light stucco or plaster mixture which consists of expanded polystyrene particles coated with an aqueous solution of methyl cellulose in addition to cement, wall binder and dispersion powders.

The embodiments of the invention in which an exclusive privilege or property is claimed are defined as follows: 
     
       1. In a process for the manufacture of a dry plaster or stucco mixture for thermal insulation consisting of foamed polystyrene particles, cement, hydraulic binders and dispersing agents, the improvement comprises coating said foamed polystyrene particles with 1 to 4% by weight of methyl cellulose, based on the weight of foamed polystyrene.
